Description

Technical Field

[0001] The utility model relates to the technical field of fluidized bed granulation, in particular to a novel fluidized bed for circulating granulation in industrial sewage treatment. Background Art

[0002] Industrial wastewater treatment is a complex process that involves removing harmful substances from wastewater to meet emission standards or achieve water reuse. Fluidized bed technology is an effective treatment method. It introduces gas or liquid into the bed to suspend solid particles and form a fluid-like state, thereby improving mass and heat transfer efficiency. Currently, when the fluidized bed is in use, hot air is directly discharged at the output port, which can easily lead to a humid working environment. In addition, the hot air also contains some particulate impurities, which will have a certain impact on the workers.

[0003] In response to the above problems, this utility model document proposes a new fluidized bed for circulating granulation in industrial wastewater treatment. Utility Model Content

[0004] The utility model provides a new type of fluidized bed for circulating granulation in industrial sewage treatment, which solves the shortcomings of the prior art that when the fluidized bed is in use, hot air is directly discharged at the output port, which easily leads to a humid working environment, and the hot air also contains some particulate impurities, which will have a certain impact on the workers.

[0005] The utility model provides the following technical solutions:

[0006] A new type of fluidized bed for circulating granulation in industrial wastewater treatment, comprising:

[0007] A bottom plate, the top of which is fixedly provided with a fluidized bed granulator body, a control host and a hot blower for use therewith, and the other end of the hot blower output pipe is connected to the inner wall of the fluidized bed granulator body;

[0008] The hot gas recovery component is installed on the fluidized bed granulator body and is used to recover the hot gas discharged from the top of the fluidized bed granulator body;

[0009] The filter assembly is installed on the hot gas recovery assembly and is used to filter and purify the gas discharged from the fluidized bed granulator body to prevent particulate impurities from affecting the health of workers.

[0010] In one possible design, the heat recovery component includes a condenser fixedly mounted on the outer wall of the fluidized bed granulator body, the input end of the condenser is connected to the top of the inner wall of the fluidized bed granulator body via an air duct, a liquid storage tank is fixedly provided on the top of the base plate, the input end of the liquid storage tank is connected to the output end of the bottom of the condenser via a liquid infusion pipe, and a drain valve is provided on the drain pipe of the liquid storage tank.

[0011] In one possible design, the filter assembly includes a filter box connected to the other end of the condenser exhaust pipe, and a particle filter and a photocatalyst filter are arranged in the filter box. Both ends of the particle filter and the photocatalyst filter are slidably installed in corresponding slide grooves, and the particle filter is arranged near the filter box input port.

[0012] In one possible design, a mounting plate is fixedly installed on the inner wall of the filter box, and an electric push rod for shaking off the sediment on the particle filter is fixedly installed on one side of the mounting plate. The output end of the electric push rod is arranged toward the center of the particle filter, and an ultraviolet lamp for promoting the recovery of the catalytic ability of the photocatalyst filter is fixedly installed on the inner wall of the filter box.

[0013] In a possible design, universal wheels are fixedly provided at the four corners of the bottom of the base plate.

[0014] In a possible design, a tubular sound-absorbing cotton for reducing noise is fixedly provided on the inner wall of the hot blower output pipe.

[0015] It should be understood that the above general description and the following detailed description are merely illustrative and do not limit the present invention.

[0016] The working principle and usage process of this technical solution are as follows:

[0017] When in use, the hot blower sends hot air into the fluidized bed granulator body through its output pipe, providing the necessary heat for the sewage treatment cycle granulation process. In the fluidized bed granulator body, the treated sewage and granulation materials are mixed, dried and granulated under the action of hot air. As the granulation process proceeds, gas containing a certain amount of heat and possible particulate impurities will be discharged from the top of the fluidized bed granulator body. The discharged hot air enters the condenser through the air guide pipe. In the condenser, the hot air is cooled and condensed into liquid, while releasing a large amount of heat energy. The condensed liquid flows into the liquid storage tank through the liquid infusion pipe for storage and subsequent treatment or reuse.

[0018] The gas treated by the condenser (the temperature has been lowered at this time, but it may still contain a small amount of particulate impurities) enters the filter box. The gas first passes through the particle filter, and most of the particulate impurities are retained on the filter. As the particles accumulate, the electric push rod will work regularly to shake off the sediment on the filter to maintain its filtration efficiency. Then, the gas continues to pass through the photocatalyst filter. Under the irradiation of the ultraviolet lamp, the photocatalyst filter catalytically decomposes harmful gases and further purifies the air. After double filtration and purification, the gas meets the emission standards and can be directly discharged into the atmosphere to ensure that it does not affect the health of the staff.

[0019] The utility model has the following beneficial effects:

[0020] The utility model recovers and reuses the hot gas generated in the granulation process through the hot gas recovery component, thereby reducing energy waste and improving energy utilization efficiency. The setting of the filter component effectively removes particulate impurities and harmful gases in the gas, avoiding potential harm to the surrounding environment and the health of workers, and meeting environmental protection requirements. The introduction of automated equipment such as electric push rods and ultraviolet lamps simplifies the equipment maintenance process and improves work efficiency.

[0021] The setting of the universal wheel of the utility model makes the movement of the equipment more flexible and convenient. The tubular sound-absorbing cotton in the output pipe of the hot blower effectively reduces the noise level when the equipment is running, improves the working environment, and protects the hearing health of the staff.

[0022] The utility model achieves multiple goals such as energy saving and emission reduction, environmental friendliness and convenient operation through a series of innovative designs, and has high comprehensive benefits. BRIEF DESCRIPTION OF THE DRAWINGS
